FLUSHING DEVICE FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 626,346, dated June 6,1899.

Application filed November 25, 1898. Serial No. 697,i43. (N model.)

T0 to whom it may concern.-

Be it known that I, DELBERT O. SEAMAN, a citizen of the United States, residing at Seattle, in the county of King and State of lVashington, have invented a new and useful Improvement in Automatically Controlled Flushing Devices for Water-Closets and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

Figure 1 isa vertical side View of a Watercloset with the seat in the position it will take when unoccupied with my device attached thereto; Fig. 2, the same view with the seat down; Fig. 3, an enlarged horizontal View of the vibrating arm with part of attachments therefor; Fig. 4, a side view of the same; Fig. 5, a vertical sectional view of the hob and attachments in a section of the guide-tube. Fig. 6 is a vertical front view of a part of tube broken off to show the bob inside.

My invention relates to improvementsin apparatus for fl ushing water-closets; and it consists of the novel construction and combination of parts hereinafter described, and pointed out in the claims.

The objects of the invention are fully set forth in connection with the following description.

1 in the drawings represents the hopper; 2, the seat; 3, the seat-hinge. The weight 4 is hung from one end of the tilting lever 5, operating on the fulcrum 12. The other end of lever is connected to the seat by means of the link 6, suspended from the seat by the hinge 10. This hinge is secured to the under side or edge of seat. The connection between the lever 5 and the link 6 is made by means of a projecting pin 7, riveted in said lever, but sliding in the slot 8 of the link. The purpose of this slot, though not essential to the operation of the device, is to permit the seat, if desired, being tilted farther back. The force of the weight l acting through the pin 7 on the upper end of slot raises the seat to the position shown in Fig. 1.

9 is a projection on end of lever to prevent the arm of said lever going over the fulcrum. The lever-arm 14 is rigidly secured to the seat and the seat is tilted up, and in its normal po sition, Fig. 1, said arm is down. To this arm is connected an end of the reach-link 1G by the pivotal pin 15, the other end of said reachlink being slotted to allow a certain movement of this reach-rod in association with the Water-closet seat independently of the vibrat ing arm 17. When the closet is not being used, the arm is in the position as shown in Fig. 1, the pin 18 on said arm projecting through the slot 19. When the seat is brought down, the lower end of said slot striking the said pin raises the vibrating arm to the position shown in Fig. 2. The seat being released, the weight 4, asserting itself, raises the said seat, pulling down the link 16, which after traveling the length. of slot in said link draws down the arm 17, engaged on the fiat top of the trigger 21, form ing a part of the chain-bob 29, carries the bob with it, thereby opening the valve in the tank, (not shown in the drawings,) and flushes the closet. The bob being drawn down by the end 38 of arm 17,Which, travelingin the arc of a circle, moves off the top 23 of trigger, Fig. 5, and releases the bob, which goes up under the force of the weight exerted by the valve in the tank through the pull-chain attached thereto until the stop on said bob strikes the top of slot 32 in the tube 22, which completes the cycle of operation, and there the bob remains by the constant upper pressure exerted on the pull-chain ready to be again pulled down to again flush the closet.

The action of the triggerin the bob will be understood from Figs. 5 and 6. The trigger reciprocating on the pin 26 in the chamber of the bob is forced inwardly to the position as indicated in broken lines, Fig. 5, by the arm 17 in its upward movement striking the inclined face 25 of the trigger. The arm having passed the trigger, the spring 28 asserts itself and forces the trigger out, as shown by full lines.

In Fig. 2 I show the vibrating arm resting on the trigger 21, the bob then being in its highest position, while in Fig. 1 the trigger is represented as just released and on the point of moving upward. The vibrating arm (shown enlarged in Figs. 3 and 4) is formed at one end with a wide striking-face 38, the other end of arm being pivoted on the pin 35 between the lugs or wings 36 36, a part of the threaded plug screwing into the socket-plate 37, fastened to the'back-board 27, to adjust the said center that a standard-size vibrating arm 17 may be adapted to any of the usual forms of water-closet backs. The tube 22, in which the bob slides, is secured to the back frame of closet, as shown, by jam-nuts or any other suitable means. This tube is slotted, as at 32 33, to allow the insertion of bob and the backward and forward movement of the trigger of bob therein. 30 is a stop made of rubber or other elastic material Lo-prevent jar and limit the upward movement of the bob in said tube.

31 is a guide and 13 a bracket for supportseat.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

prising a Weight; a lever; and link all for the purposes set forth and described.
